Cob and Adobe Intensive, September 1 – 3, 2012. Instructors Michael G. Smith and Massey Burke. This hands-on course immerses students in two important forms of earthen construction, cob and adobe. Adobe, one of the world’s oldest and most widespread building techniques, refers to the use of sun-dried blocks of clay soil, fiber, and sand to build up a wall. These blocks can be arranged in various ways for different kinds of structural strength in a building. Cob, also known as monolithic adobe, is a combination of clay soil, straw, and sand, hand-formed in place on the wall while the mix is still moist and sculptable. The two techniques are complementary in construction: each expands the possibilities of the other. In this course we will learn about soil evaluation for construction, mixing techniques and recipes, basic adobe and cob design and construction principles. There will be a special emphasis on arch-building using both formwork and corbeled techniques. The class will construct the side and end walls of a Nubian vault (see next course for more information about this structure.) $275, or $250 if you pay in full by August 1.

Nubian Vault Intensive, September 17 – 21, 2012. Instructor Stevan de la Rosa. In this course students will construct a Nubian vault, an ancient form of adobe structure that originated in Egypt, was rediscovered and popularized by populist architect Hassan Fathy, and is currently enjoying an international revival, especially in areas with very little wood availability. A Nubian vault enables the builder to create an arched vault (or a dome) without using any formwork, which means you can completely enclose a space using no wood whatsoever. This particular vault will be reinforced with bamboo to stabilize the adobe for the seismic loads of California. In addition to basic adobe masonry and hands-on vault construction, this workshop will cover Nubian vault design, roofing/waterproofing options, arch layout and construction, earthen mortars and plasters. Previous earthen construction experience is helpful but not required; students with no experience should consider attending the Cob and Adobe Intensive in August. $500, or $450 if you pay in full by August 15.

Both workshops will be held at Spreadwing Farm in Rumsey, California.
